Pattern description

The subject of the utility model is a door leaf, used especially in residential buildings.

The commonly known door leaves have a rectangular frame consisting of vertical and horizontal rails, on which a smooth panel or a panel with one or more panes embedded in it is mounted.

The door leaf, known from the Polish description of the utility model No. PL66906, has a rectangular frame with a panel and a mirror embedded in it, and between the panel and the mirror there is a metal plate to which the mirror is glued.

It is also known from the Polish patent specification No. PL214392 a door leaf with a support plate covered on both sides with decorative panels and provided with at least one opening covered from the outside and inside with glass joined by spacers, the edges of these glass panels being covered with decorative panels protruding beyond the edges of the support plate and, moreover, the periphery of the inner pane is wider than the periphery of the outer pane and is supported on the periphery of the carrier plate and fixed thereto with screws. On the other hand, the composite exterior door known from the Polish patent specification No. PL66791 is equipped with a door leaf, which is an external frame made of two horizontal wooden stiles, the ends of which are topped with two vertical wooden stiles, next to which there are longer vertical elements of a rectangular steel frame, the hollow interior of which is filled with a thermal insulation material in the form of polyurethane foam, the shorter sides of which are adjoined by horizontal wooden rails, and inside the steel frame, in its middle part, two vertically positioned wooden stiffening ribs. In turn, to these stiffening ribs and to both end walls of these wooden rails and to the wooden frame, a waterproof plywood sheathing, preferably made of an "Exterior" board, is attached, while the chambers formed between these elements are filled with thermal insulation material such as mineral wool, polystyrene or foam. polyurethane. In addition, both panels have a pass-through opening with double-sided glazing, while all the rails of this wing have a rebate on their perimeter, while one of the vertical rails is equipped with sleeve elements for hinges, and the other with a handle with a plate and a mortise lock.

The purpose of the utility model is to develop a much simpler and cheaper door leaf structure, enabling its quick assembly, with increased thermal insulation, including acoustic insulation, and without thermal bridges.

The door leaf according to the utility model is characterized by the fact that its internal rectangular frame made of hard wood-based material, filled inside with heat-insulating material together with wood-based panels covering it on both sides, constitute the central panel of this leaf, and both vertical stiles of its rectangular frame are connected to two additional vertical external stiles, also made of hard wood-based material with the use of pins embedded in the openings, made in the side walls of both external vertical stiles and in the openings in the side walls of both vertical internal stiles, and with the help of grooves also made in the side walls of both vertical internal stiles, in which the projections of the side walls of both external vertical stiles are embedded. In addition, its central plate unit has three openings, arranged vertically below each other, covered on both sides with glass plates, which are embedded in the grooves of profile inserts, also made of hard wood-based material, adjacent to the thermal insulation material of this central unit filling this unit. Preferably, the rectangular frame of the central panel unit and the outer vertical two rails connected thereto are made of a wood-based material of the MDF, HDF type, and the filling of this rectangular frame is made of linen board, chipboard or cellular board with a honeycomb filling.

The use of a tongue / groove connection in this sash and its central plate assembly with both extreme vertical stiles simplified its assembly significantly, while ensuring the certainty of this connection.
